Asia Bolts Industries LLC has manufactured fasteners from Dubai Investment Park since 1997. We make and supply anchor bolts to contractors, EPC companies, steel fabricators and plant owners across the UAE, Saudi Arabia, Qatar, Kuwait, Oman and Bahrain.
Our cast-in-place anchor bolts are made to ASTM F1554 Grades 36, 55 and 105, plus alloy, stainless and metric grades, in diameters from M6 to M150 (1/4" to 6"). Every order ships with material test certificates and full heat-number traceability — see our ISO certifications and approvals.
What Are Anchor Bolts?
Anchor bolts connect structural steel, equipment and machinery to concrete foundations. They carry tension, shear and uplift loads from columns, base plates, pipe racks, tanks, turbines, pumps and compressors into the foundation. A poorly specified or corroded anchor bolt can put a whole structure at risk, so grade, coating and embedment length need to be right for the project.
Types of Anchor Bolts We Manufacture
Cast-in-Place Anchor Bolts (ASTM F1554)
J Bolts
Hooked at one end for embedment in concrete. Common for light structures, signage, fences and general foundations.
L Bolts
Bent at 90° for structural columns, base plates and equipment bases.
Straight / Headed Anchor Bolts
Headed or double-nutted bolts for structural steel and heavy base plates.
Foundation Bolts
Heavy-duty anchors for turbines, compressors, pumps and large machinery.
Anchors with Plates, Sleeves or Templates
Made to drawing for precise positioning during the pour.
Threaded Rod & Double-End Anchors
Cut and threaded to your length and thread specification — see our threaded bars.
Post-Installed Anchors (Supplied for Retrofit and Secondary Fixings)
Wedge Anchors (Mechanical Expansion)
Sleeve Anchors
Chemical (Resin) Anchors
ASTM F1554 Grades at a Glance
ASTM F1554
Yield grades, minimum properties and typical applications
| Grade | Min. Yield | Typical Application |
|---|---|---|
| Gr. 36 | 36 ksi (250 MPa) | General construction, base plates, light to medium structures |
| Gr. 55 | 55 ksi (380 MPa) | Higher-strength structural connections; weldable when supplementary requirement S1 is specified |
| Gr. 105 | 105 ksi (725 MPa) | Heavy-duty foundations, high uplift and seismic loads |
Matching nuts are normally ASTM A563 (Grade A for Gr. 36/55 and Grade DH for Gr. 105) — see our full range of anchor bolt nuts. Standard threads are UNC Class 2A, or 8UN for larger diameters.

Coatings for GCC Conditions
High humidity, salt-laden coastal air, sabkha soil and intense heat corrode unprotected steel quickly. We apply:
Hot-Dip Galvanizing
Zinc-Nickel
Zinc Flake
Electro Zinc Plating
Zinc Bichromate
Tectyl
Molykote
Self-Color / Black
Stainless Steel
- Hot-dip galvanizing: the standard choice for external and exposed foundations
- Zinc-nickel and zinc flake: higher corrosion resistance for offshore and chemical sites
- Tectyl and Molykote: corrosion protection and anti-seize
- Self-color / black: for indoor or embedded use
- Stainless steel: for the most aggressive environments
Engineering note: for high-strength grades such as Gr. 105, discuss
galvanizing or plating with us first to manage hydrogen embrittlement risk.

Frequently Asked Questions
What is the difference between ASTM F1554 Grade 36, 55 and 105?
They differ in yield strength: 36, 55 and 105 ksi. Grade 36 suits general construction, Grade 55 suits higher-strength connections and can be welded when S1 is specified, and Grade 105 is for heavy-duty, high-load foundations.
What is the difference between J bolts and L bolts?
J bolts have a curved hook and L bolts have a 90° bend. Both rely on bond and mechanical embedment. L bolts are usually specified for structural columns and machinery, and J bolts for lighter applications.
Can anchor bolts be hot-dip galvanized?
Yes. Galvanizing is the most common protection for external foundations in the GCC. Nuts must be tapped oversize to allow for the coating, and high-strength grades need hydrogen embrittlement precautions.
Which anchor bolt material is best for coastal or offshore sites?
Hot-dip galvanized or zinc-nickel coated carbon steel is common, while A193 B8M (316) stainless suits the most severe conditions.
Do you make anchor bolts to custom drawings?
Yes. We manufacture to your drawing for length, bend radius, thread length, plates, sleeves and templates.
Do you supply certificates?
Yes. Material test certificates (EN 10204 3.1, and 3.2 on request) and traceability documents come with every order.
Do you deliver outside the UAE?
Yes. We supply Saudi Arabia, Qatar, Kuwait, Oman and Bahrain.
